GANTT (planing) view access

Hi,

I tried to search form as well as online doc and if i'm only not blind man there is nothing about this.

My problem is, I have user profile defined on which all is working fine. I created another profile with --as far as I tried-- the same settings (according access rights) as previous profile but I cannot make PLANING (GANTT) view working.

I can open planing view I see view, toolbar, I can even calculate planing but view is empty, no planing (as main line), no any activities.

Of course I have added user of this profile into project as resource... even if I define profile inside project as Administrator result is the same.

Planing portfolio display project nice, I see project, mailstones.

When I open projects view I see my project, I can open it and modify.

All is fine except planing view.

So, my question is... is there any access right I could missed ? How about customization (in our company there is customization plugin installed) - is it possible that it comes from customziation plugin ?

Yes, there were error in log and base on them I found workarround on forum.

Thanks for info.
